- the invention is based on an ischarm for a windshield wiper according to the preamble of claim 1.
- Known windshield wipers have a wiper arm which consists of a fastening part and an articulated part connected to it with a wiper rod.
- a wiper blade is articulated to this, which is usually constructed from a wiper strip carrier with a wiper strip.
- the joint part has a spring chamber for a tension spring.
- the spring chamber is open towards the windshield and has a hanging device, for example an eyelet, towards the wiper rod, into which a retaining bracket of the tension spring is suspended.

Description
Wischarm für einen ScheibenwischerWiper arm for a wiper
Stand der TechnikState of the art
Die Erfindung geht von einem ischarm für einen Scheibenwi- scher nach dem Oberbegriff des Anspruchs 1 aus.The invention is based on an ischarm for a windshield wiper according to the preamble of claim 1.
Bekannte Scheibenwischer besitzen einen Wischarm, der aus einem Befestigungsteil und einem damit gelenkig verbundenen Gelenkteil mit einer Wischstange besteht. An diese ist ein Wischblatt angelenkt, das in der Regel aus einem Wischleistenträger mit einer Wischleiste aufgebaut ist.Known windshield wipers have a wiper arm which consists of a fastening part and an articulated part connected to it with a wiper rod. A wiper blade is articulated to this, which is usually constructed from a wiper strip carrier with a wiper strip.
Das Gelenkteil weist an seinem Ende, das dem Befestigungsteil zugewandt ist, eine Federkammer für eine Zugfeder auf. Die Federkammer ist zur Windschutzscheibe hin offen und hat zur Wischstange hin eine Einhängevorrichtung, z.B. eine Öse, in die ein Haltebügel der Zugfeder eingehängt ist. Das andere Ende der Zugfeder greift in einen c-förmigen Bügel, der an einer Einhängevorrichtung des Befestigungsteils einge- hängt ist. Der c-förmige Bügel kann auch an der Zugfeder angeformt sein. Das Gelenkteil stützt sich über eine Nabe an einem Gelenkbolzen des Befestigungsteils ab. Das so gebildete Gelenk, auch Abklappgelenk genannt, und die Einhangevorrichtung der Zugfeder sind so zueinander angeordnet, dass die Zugfeder das Gelenkteil und die Wischstange in Richtung einer Windschutzscheibe zieht. Das Wischblatt liegt somit unter der Kraft der Zugfeder an der Windschutzscheibe an und wird durch diese in der Betriebsstellung begrenzt.At its end, which faces the fastening part, the joint part has a spring chamber for a tension spring. The spring chamber is open towards the windshield and has a hanging device, for example an eyelet, towards the wiper rod, into which a retaining bracket of the tension spring is suspended. The other end of the tension spring engages in a c-shaped bracket which is hooked onto a hooking device of the fastening part. The c-shaped bracket can also be molded onto the tension spring. The joint part is supported by a hub from a hinge pin of the fastening part. The joint formed in this way, also called the folding joint, and the hooking device of the tension spring are arranged relative to one another such that the tension spring pulls the joint part and the wiper rod in the direction of a windshield. The wiper blade is thus under the force of the tension spring on the windshield and is limited by this in the operating position.
Zum Reinigen oder zur Montage des Wischblatts wird das Ge- lenkteil des Scheibenwischers von der Windschutzscheibe abgeklappt. Dazu wird das Gelenkteil um das Abklappgelenk geschwenkt, wobei im Bereich eines Abklappwinkels von ca. 60 bis 80° zunächst die Spannung der Zugfeder überwunden werden muss. In der Abklappstellung zieht die Feder das Gelenkteil nicht mehr zur Fahrzeugscheibe, sondern zieht eine am Gelenkteil angeformte Anlageflache oder den c-formigen Bügel in Abklapprichtung gegen einen Begrenzungsanschlag am Befe- stigungsteil . Zum Zuruckklappen des Wischblatts an die Windschutzscheibe muss das Gelenkteil wieder mit einer definier- ten Kraft um die Gelenkachse geschwenkt werden.To clean or assemble the wiper blade, the articulated part of the wiper is folded down from the windshield. For this purpose, the joint part is pivoted about the folding joint, the tension of the tension spring first having to be overcome in the region of a folding angle of approximately 60 to 80 °. In the folded-down position, the spring no longer pulls the joint part towards the vehicle window, but pulls a contact surface formed on the joint part or the C-shaped bracket in the folding direction against a limit stop on the fastening part. To fold the wiper blade back onto the windshield, the joint part must be pivoted around the joint axis again with a defined force.
Um die aerodynamischen Eigenschaften eines Fahrzeugs zu verbessern, werden die Scheibenwischer in ihrer Parkstellung zunehmend verdeckt in einer so genannten Haubenspalte zwi- sehen der Motorhaube und der Windschutzscheibe abgelegt. Eine solche Wischeranlage ist z.B. aus der DE 38 10 017 AI bekannt. Damit das Gelenkteil beim Abklappen mit dem üblichen Winkel an der Motorhaube nicht anschlagt und diese beschädigt, ist ein Begrenzungsanschlag vorgesehen, der ein Ab- klappen nur in einem kleineren Winkelbereich zulaßt, in dem die Zugfeder noch keine Kraft in Abklapprichtung erzeugt. In dieser Abklappstellung, die zwar zum Reinigen der Windschutzscheibe ausreicht, aber einen Wechsel des Wischblatts erschwert, wird das Gelenkteil mit einer Federraste gehalten, die durch die Zugfeder und eine Nocken-Schulteranord- nung gebildet wird.In order to improve the aerodynamic properties of a vehicle, the windshield wipers are placed increasingly concealed in a so-called hood gap between the hood and the windshield in their parking position. Such a wiper system is known for example from DE 38 10 017 AI. So that the articulated part does not hit the bonnet at the usual angle and damage it, a limit stop is provided which only allows it to be folded down in a smaller angular range in which the tension spring does not yet generate any force in the folding direction. In In this fold-down position, which is sufficient for cleaning the windshield, but makes it difficult to change the wiper blade, the joint part is held with a spring catch which is formed by the tension spring and a cam-shoulder arrangement.
Manche Abklappgelenke, z.B. nach der DE 37 09 994 AI, besitzen eine mit dem Befestigungsteil fest verbundene, zum Gelenkteil hin offene Nabe, in die eine mit dem Gelenkteil fest verbundene, bolzenförmige Gelenkachse eingreift. Im eingebauten Zustand wird das Gelenkteil mit dem Wischblatt in der Betriebsstellung durch die Nabe und die Fahrzeug- scheibe und in der Abklappstellung durch die Nabe und den Begrenzungsanschlag in einer stabilen Lage gehalten. Demzu- folge besteht keine Gefahr, dass es zur offenen Seite der Nabe heraus gedreht wird.Some hinges, e.g. according to DE 37 09 994 AI, have a fixedly connected to the fastening part, towards the joint part open hub into which engages a bolt-shaped joint axis firmly connected to the joint part. When installed, the joint part with the wiper blade is held in a stable position by the hub and the vehicle window in the operating position and by the hub and the limit stop in the folded-down position. As a result, there is no danger of it being turned out to the open side of the hub.
Im vormontierten Zustand, beispielsweise zum Transport, besteht die Gefahr, dass durch geringe Krafteinwirkung auf den vormontierten Wischarm, z.B. durch Erschütterungen während des Transports oder unvorsichtige Handhabung, die Gelenkachse aus der Nabe heraus gleitet und das Abklappgelenk in seine einzelnen Bestandteile auseinander fällt. Dadurch werden zusätzliche Montagearbeiten notwendig und es besteht die Ge- fahr, dass Teile verloren gehen.In the preassembled state, for example for transport, there is a risk that the preassembled wiper arm, e.g. due to vibrations during transport or careless handling, the joint axis slides out of the hub and the folding joint falls apart into its individual components. This means that additional assembly work is necessary and there is a risk that parts will be lost.
Vorteile der ErfindungAdvantages of the invention
Nach der Erfindung ist zwischen der Betriebsstellung und der Abklappstellung eine Raststellung vorgesehen, bis zu der das Wischblatt in einer Parkposition von der Windschutzscheibe abgehoben werden kann, ohne die Motorhaube zu berühren . Zur Montage eines Wischblatts wird der Scheibenwischer aus der Parkposition in eine Montageposition gestellt, in der ohne Beschädigung der Motorhaube die Raststellung überdrücht werden kann und das Gelenkteil die Abklappstellung mit einem Abklappwinkel erreicht, in der das Wischblatt leicht zu montieren ist. In der Parkposition wird das Gelenkteil in einer Zwichenstellung fixiert, die eine Beschädigung der Motorhau- be ausschließt aber gleichzeitig genügend Freiraum zum Reinigen des Wischblatts bzw. der Windschutzscheibe bietet. Vorteilhafterweise ist diese Stellung als Raststellung ausgebildet, so dass der Wischarm sicher in dieser Position gehalten wird und nicht ungewollt an der Motorhaube anschlägt oder ohne Wischblatt auf die Windschutzscheibe zurück schlägt .According to the invention, a latching position is provided between the operating position and the folding position, up to which the Wiper blade can be lifted off the windshield in a parking position without touching the bonnet. To install a wiper blade, the windshield wiper is moved from the park position into an assembly position in which the detent position can be overwhelmed without damaging the bonnet and the articulated part reaches the fold-down position with a fold-down angle in which the wiper blade is easy to install. In the park position, the joint part is fixed in an intermediate position, which prevents damage to the bonnet but at the same time offers enough space for cleaning the wiper blade or the windshield. This position is advantageously designed as a latching position, so that the wiper arm is held securely in this position and does not strike the bonnet unintentionally or strikes back on the windshield without a wiper blade.
Um die Raststellung des Scheibenwischers zu ermöglichen, sind vorteilhafterweise nur geringfügige Veränderungen an den üblichen Standardbauteilen notwendig. Das erfindungsge- mäße Befestigungsteil weist an seinem Ende, das dem Gelenkteil zugewandt ist, eine Rastbahn auf, die zweckmäßigerweise beim Herstellen des Befestigungsteils angeformt wird. Als Veränderung gegenüber dem Standardbauteil wird am Ge- lenkteil eine Federraste befestigt. Diese ist zweckmäßigerweise in der Federkammer des Gelenkteils angeordnet und zwar seitlich versetzt zu dem c-förmigen Bügel bzw. der Zugfeder.In order to enable the locking position of the windshield wiper, advantageously only minor changes to the usual standard components are necessary. The fastening part according to the invention has at its end, which faces the joint part, a latching path which is expediently molded on when the fastening part is being manufactured. As a change from the standard component, a spring catch is attached to the joint part. This is expediently arranged in the spring chamber of the joint part and that laterally offset from the c-shaped bracket or the tension spring.
Die Federraste weist zweckmäßigerweise als federndes Element eine Federzunge auf, die mit einem Winkelteil an einer Seitenwange des Gelenkteils befestigt ist. Die Federzunge ist so angeordnet, dass sie beim Schwenken des Wischarms in die Raststellung die Rastbahn des Wischarms berührt und in eine Rastvertiefung eingreift. Dabei sind die Formen der Federzunge und der Rastvertiefung so aufeinander abgestimmt, dass der Wischarm in beiden Schwenkrichtungen über einen Begrenzungsnocken gedrückt werden muss, um in die Abklappstellung oder in die Betriebsstellung zu gelangen. In der Betriebsstellung berührt die Federzunge das Befestigungsteil nicht oder nur unwesentlich, so dass die Auflagekräfte des Wisch- blatts praktisch nicht verändert werden.The spring catch expediently has a spring tongue as a resilient element, which is fastened with an angle part to a side cheek of the joint part. The spring tongue is Arranged so that when the wiper arm is pivoted into the latching position, it touches the latching path of the wiper arm and engages in a latching recess. The shapes of the spring tongue and the locking recess are coordinated with one another in such a way that the wiper arm has to be pressed in both pivoting directions via a limiting cam in order to reach the folded-down position or the operating position. In the operating position, the spring tongue touches the fastening part only slightly or not at all, so that the contact forces of the wiper blade are practically unchanged.

Beschreibung der AusführungsbeispieleDescription of the embodiments
Ein Wischarm 10 umfasst ein Befestigungsteil 12 und ein Ge- lenkteil 18 mit einer Wischstange 22, mit der ein Wischblatt 34 gelenkig verbunden ist (Fig. 1) . An einem Ende weist das Befestigungsteil 12 eine Aufnahmebohrung 14 für eine nicht dargestellte Antriebswelle des Scheibenwischers auf. Am anderen Ende ist das Befestigungsteil 12 mit dem Gelenkteil 18 durch ein Abklappgelenk 54 gelenkig verbunden. Beide Teile sind in der gezeigten Betriebsstellung durch eine Zugfeder 26 gegeneinander verspannt. Dazu ist die Zugfeder 26 an einem Ende 28 in eine Einhängevorrichtung in Form einer Einhängeöse 24 an der Wischstange 22 und am anderen Ende 30 über einen c-förmigen Bügel 32 in einer Einhängevorrichtung in Form eines Querstifts 16 am Befestigungsteil 12 eingehängt (Fig. 2) .A wiper arm 10 comprises a fastening part 12 and a joint part 18 with a wiper rod 22, to which a wiper blade 34 is connected in an articulated manner (FIG. 1). At one end, the fastening part 12 has a receiving bore 14 for a drive shaft, not shown, of the windshield wiper. At the other end, the fastening part 12 is connected in an articulated manner to the joint part 18 by a folding joint 54. In the operating position shown, both parts are braced against one another by a tension spring 26. For this purpose, the tension spring 26 is suspended at one end 28 in a suspension device in the form of a suspension eye 24 on the wiper rod 22 and at the other end 30 via a c-shaped bracket 32 in a suspension device in the form of a transverse pin 16 on the fastening part 12 (FIG. 2) ,
Im Bereich des Abklappgelenks 54 weist das Gelenkteil 18 einen u-förmigen Querschnitt auf, in dessen innerem Raum .die Zugfeder 26 untergebracht ist. Neben der Zugfeder 26 bzw. dem c-förmigen Bügel 32 ist eine Federraste 36 angeordnet, die durch eine Federzunge 40 gebildet und mit einem Wdnkel- teil 38 an einer Seitenwange 20 des Gelenkteils 18 befestigt ist. Ein als Rastende 42 geformter Teil der Federzunge 40 weist in Richtung auf eine Rastbahn 46 am Befestigungs teil 12. Damit die Auflagekraft des Wischblatts 34 auf der Windschutzscheibe nicht beeinflusst wird, ist die Federzunge 40 so gestaltet bzw. eingebaut, dass sie in der Betriebsstel- lung von der Rastbahn 46 abhebt.In the area of the folding joint 54, the joint part 18 has a U-shaped cross section, in the inner space of which the tension spring 26 is accommodated. In addition to the tension spring 26 or the c-shaped bracket 32, a spring catch 36 is arranged, which is formed by a spring tongue 40 and is fastened with a winding part 38 to a side cheek 20 of the joint part 18. A part of the spring tongue 40 shaped as a latching end 42 points in the direction of a latching track 46 on the fastening part 12. So that the contact force of the wiper blade 34 on the windshield is not influenced, the spring tongue 40 is designed or built in such a way that it lifts off the latching track 46 in the operating position.
Der Wischarm 10 befindet sich in seiner Parkposition in einer so genannten Haubenspalte zwischen der Windschutzscheibe und einer nicht dargestellten Motorhaube. Fig. 4 zeigt das Abklappgelenk 54 in einer Raststellung, bis zu der dasThe wiper arm 10 is in its parking position in a so-called hood gap between the windshield and an engine hood, not shown. Fig. 4 shows the hinged joint 54 in a locking position up to which
Wischblatt 34 in der Parkposition des Scheibenwischers abgehoben werden kann, ohne die Motorhaube zu berühren. Dazu wird das Gelenkteil 18 um den Gelenkbolzen 52 geschwenkt und das Rastende 42 der Federzunge 40 gleitet an der Rastbahn 46 entlang, bis es in einer Rastvertiefung 44 einrastet.Wiper blade 34 can be lifted off in the parked position of the windshield wiper without touching the bonnet. For this purpose, the hinge part 18 is pivoted about the hinge pin 52 and the latching end 42 of the spring tongue 40 slides along the latching track 46 until it snaps into a latching recess 44.
Die Rastvertiefung 44 wird von zwei Nocken 56 und 58 begrenzt. Beim Überwinden dieser beiden Nocken 56, 58 erhöht sich die Spannung der Federzunge 40, so dass das Rastende 42 der Federzunge 40 sicher in der Rastvertiefung 44 gehalten wird und der Wischarm 10 in der Raststellung fixiert ist. Das Gelenkteil 18 mit dem Wischblatt 34 ist in dieser Stellung weit genug von der Windschutzscheibe entfernt, um z.B. das Wischblatt 34 und die Windschutzscheibe zu reinigen. Zum Wechseln des Wischblatts 34 wird der Wischarm 10 aus der Parkstellung in eine Position gefahren, in der das Gelenkteil 18 weiter abgeklappt werden kann. Dabei wird der Nocken 58 überwunden und die Federzunge 40 gleitet an der Rastbahn 46 entlang bis die Abklappstellung erreicht ist (Fig. 3), in der die Zugfeder 26 auf das Gelenkteil 18 eine Kraft in Abklapprichtung erzeugt und das Gelenkteil 18 oder den c-förmigen Bügel 32 gegen einen Anschlag zieht. The locking recess 44 is delimited by two cams 56 and 58. When these two cams 56, 58 are overcome, the tension of the spring tongue 40 increases, so that the latching end 42 of the spring tongue 40 is held securely in the latching recess 44 and the wiper arm 10 is fixed in the latching position. The joint part 18 with the wiper blade 34 is in this position far enough from the windshield, for example, to clean the wiper blade 34 and the windshield. To change the wiper blade 34, the wiper arm 10 is moved from the park position into a position in which the joint part 18 can be folded down further. The cam 58 is overcome and the spring tongue 40 slides along the latching path 46 until the fold-down position is reached (FIG. 3), in which the tension spring 26 on the joint part 18 is one Generated force in the folding direction and pulls the hinge part 18 or the c-shaped bracket 32 against a stop.
